Aircraft Family Design Using Decomposition-Based Methods

This paper explores the use of decomposition-based methods for aircraft family design. The traditional approach in multidisciplinary design optimization is to decompose a problem along disciplinary lines. For aircraft family design problems, a more natural approach is decomposition by individual aircraft. This decomposition facilitates the concurrent development of several aircraft variants, pr...

Improving Web Design Methods with Architecture

Many approaches have been developed for modeling the functional aspects of Web applications, but there is a lack of a modeling language for their architectural concerns. This paper proposes such a modeling language defined as a UML 2.0 profile, which allows the specification of domain-specific models for the architectural view of Web applications. The profile is part of the Web Software Archite...

Uncertainty and Sensitivity Analysis Methods for Improving Design Robustness and Reliability

Engineering systems of the modern day are increasingly complex, often involving numerous components, countless mathematical models, and large, globally-distributed design teams. These features all contribute uncertainty to the system design process that, if not properly managed, can escalate into risks that seriously jeopardize the design program. In fact, recent history is replete with example...

Improving Software Robustness with Dependability Cases

Programs fail mainly for two reasons: logic errors in the code, and exception failures. Exception failures can account for up to 2/3 of system crashes [6], hence are worthy of serious attention. Traditional approaches to reducing exception failures, such as code reviews, walkthroughs and formal testing, while very useful, are limited in their ability to address a core problem: the programmer’s ...
